GAS-BURNING APPARATUS.

Specification of Letters Patent.

Iia tented Sept. 30,1913.

Application filed October 18, 1912. Serial No. 726,464.

To (ZZZ LU/1077a it may concern Be it known that l, PETER Frrn, a subject of the King of the United Kingdom of Great Britain and lreland, and residing at Glasgow, Scotland, have invented a certain new and useful Improvement in tiasllurrp ing Apparatus, of which the following is a speeili nitioti.

This invention relates to the consumption of gas or gaseous mixtures in gas burning apparatus in which granular material is employed to divide the gas up into minute streams.

The object or my invention is to construct a gas burning apparatus of this type more partieularly adapted for application to domestic firegr: ten, ranges, stoves, hoilera, heaters and the like which will eonsome gas at pressurea of ordinary supply under the control of a co k or cooks and in which an equalized radiant; el'l'eet over the entirti surface area of the tire is atlordtuli with a minimum of gas (JODSllIYlPl'lOfl and a maximum of heat production. i also aim at producing a gas fire which will approxh mate closely both in appearance and utility to an ordinary coal tire and which will have continuous heating surface of substantially the dimensions of the fuel container lire-grate or the like into which it. is titled.

A. further object of my invention is to dispense entirely with an aggregation of separate gas or burners arranged with in the fuel eiimtainer, tire-grate or the like.

in a burning apparatus eonslrui-ted according to my in motion l. employ a rhaup her or chambers or a. pan or rreeptaele or any eonrenient: shape and oi any suitahle unite ial, into Wllit'll l eondurt a romhustihle mixture of gas and air. Within the ehanr her or pan, and at: a suitahle distanrtfrom the bottom thereof, l arrange a sheet of line wire gauze, coarse linen, huekram, or the like, suitahly impregnated so as to he rendered uon-intlamrnahle, (or l may use a pertoratijwl plate.) which serves the douhle purpose of noting as I support; for the loose nonenuhustihle material to he hereinatter tlt-ao-ril-nd and also for preventing tiring hack into the pan. Maire the gauze l place a lay o l loose iioil-remhinltihle one terial, aurh as hoarse aaud, tine gravel or slog. uuarla Cllil ll i sifted tire--olay, asbestos p:1l*t-i.rle.--, or any other suitahle loose noneomhustihle snhstnnee; or in order "to facilitote the tiasiaage oi? the gasoline mixture may ad 'antageouslv employ small spherical hodies such as iron shot, glass heads and the like. When a comhustihle mixture is led into the pan it passes through the gauze or the like, pereolates through the loose nonr-omhuslihle material (\rhioh oll'ers little or no resistance to the passage of the oomhusth hle mixture, thus enabling gas at. the ordinary pressure to he employed), and is clivided into an infinite mnnher of streams. When ignited the gaseous mixture hurns evenly with a hot hlue tlame over the entire surface of the loose material. l may, if desired, place a thin layer of ashestos wool or otherlire-resisting material, in a state ol tine division, over the entire arm of the loose material in a pan. This material is ot Slll'll a nature that when highly heated is ait'ords a luminous surface ol high radiative r-apat'ity.

gas tun-hing apparatus constructed as above deserihed, when in operation, approxi mates very closely in appearance to an ordiuary coal lire, and can he used for heating Wiltll or l'or cooking purposes generally in the same manner as an ordinary real fire, while small, articles of a eomhustihlo nature, sun-h as scraps of paper, clear and (cigarette ends and the like may he consumed upon its surl'al-e without any (lelelerituis ell'et't on the ellhiemy of the tire. poker or other inslruuu-nlmay also he inserted into the tire and the non-romhustihle ma-- lerial. stirred ahoul without doing any in jury. in order to protevl the gauze or hoarse lain-ii: .t'rom po.- -=ihle injury l may plarr a metal grating or the like upon it.

In the aeeompanying dra wines which illustrate various UHlllUtliHlllIll-l hi my invention. Figures 1 and it show a Ht'llfllltll elevation and plan resperlively ol'a ,o'ashurning apparatus emlnnlying the present invention and applied to a modern interior grrate. Figs. 3 to 9, ineluaive, are seeiionnl elevations, to he luj reinal'ler rel't-rred to, showing (lllllltllt l'orms ot the invention.

ltehta'riiur lirst to Fig t and 3, is a pan or remplaele whit-h is made to fit the spare between the lire-hriek hack and sides ll and the east-iron 'l'ronl ol? the lire-grate. l) is a ledge or support for the wire frame revered with line wire naure, (.(Mll'Sll linen huekrani or like material l (l is a layer of loose nonmemlumtihie material in a state of line tlisinte rratiojn, which lills the space hetzwrmi the "Wire game ano the top of the ing a passage for the combustible gaseo smixture.

2. In a gas burnin" apparatus, the combination of areceptace havlng an inlet, and

also having an exit at which latter combnstion takes place a Bunsen nozzle at said inlet for supplyinga combustible mixture of gas and air to the interior of said receptacle, a foraminous element arranged Within said receptacle, said element affording the sole means for the passage of both the gas and th e air toward said exit, a'layer of fire-resisting material in a state of fine division, granular non-combustible material interposed between said foraminous element and said fire-resisting material and affording a passage for the combustible gaseous mixture, said granular material being located outside of the field of combustion, and means for retaining the said non-combustible and thefire-resisting materials in position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
